Burn, Diesel, and Mamba are pretty close in design. All are semi-planing, around the same length, volume, and rocker. They'll paddle just slightly different, but the general concept is pretty much the same.
I really like my 2010 Burn (the new version). I also have paddled my wifes mamba. The mamba felt VERY familiar. I'd say the mamba felt a bit more forgiving, but they both paddled similarly. I have not paddled a Diesel because nobody around here caries wavesport, but from everything I have seen/read, it is a very similar boat as well.
For those saying remix.....It's not similar to a mamba. It's a great boat, but it is not similar to a mamba.
